8 (Cl. fi l lilil) The invention relates to apparatus for improvthe and mining drift. In these slushing ing the operation or and has particular operations, they are known, it is therefore application to means for deflecting the main necessa e apparatus for location at the haulage rope of the scraper around a corner to junctio. 1 he slice with its ruining drift, which facilitate the slushing of ore in mines. will allow or th main haulage cable and 59 The invention contemplates the provision of also the l and tail ropes connecting with the apparatus for changing the ction of travel scraper. of the scraper and more s es sally apparatus Referring more particularly to Figures 2, 3 and for attachment to a post or other support to ent the improved apparatus of the invention is .1 able the haulage cable of the scraper to pass shown comprising a supporting member around a corner whereby the scraper may have formed of a plurality of members, each having a an uninterrupted travel, as, for example, from a right bend to provide securing flanges 16 raise in a mining drift to the working face of the an l? and cooperating horizontal flanges 18 and slic which leads at ri ht angles from the drift. l9. Flange 18 has a centrally cutout portion 20 I 15 Accordingly, an object of the invention resides in providing side sections which are reinforced by re the provision of a system of ro ers arranged to the flanges e ri ht angle members are deflect a cable at right .ngles and which suitably sec d together as y W n the 00mwill also allow of lead and tail ropes pieed unit being fastened to apostor-other supspliced to the haulage cable and which join a porting structure 21 by securing chains 22 having 3 or other device to the cable. connectio'i at their to the eye bolts 23 and With these and various other objects in view, A lolt through one of the flanges the invention may consist of certain novel features 1'7 and also through flange 16 to one side of the of construction and operation as will be more center thereof, while a bolt 24 having threaded fully described and particularly pointed out in the connection with nut on the end of the chain specification, drawings and claims appended passes .irough the other flange 17 and through hereto. flange 16 to the other side of the center. This In the drawings which illustrate an embodidisposition of the securing chains locates the ment of the device and. wherein like reference same in spaced relation on the supporting post 21, characters are used to designate like partswhich therefore engage with the supporting Figure 1 is a plan view of a portion of an ore member 15 at the upper and lower extremities of mine showing the use of the invention for directthe member so that the same is securely held in ing the scraper from the working face of the slice place, being prevented from rotatlve or bodily to the slusher hoist; shifting movements.

Locating the horizontal roller As a slice is often at some distance from a raise centrally of flange 16 positions the same between scrapers 13 are commonly employed for transthe vertical rollers and it will be noted that the porting the ore from the Working face 14 of the outer edge of the horizontal roller extends inslice to the raise, which involves travel or the wardly to intercept the vertical plane formed by scraper around the 'ight angle corner formed by the inner edge of the vertical rollers. Since the v ca latter are vertically adjustable through rotation of studs 28 they have a variety of positions with respect to the horizontal roller, their exact location being determined by the slack existing in the main haulage cable.

Secured to the sides of flange 18 by means of the depending lugs 35 are slap rollers 36. Each roller is angularly disposed with respect to the side edge of the flange 18, being adapted to engage the haulage cable and to limit the upward movement of said cable. The structure shown is preferred, although the rollers may be replaced by horizontal flanges on the upper end of the vertical rollers without affecting the efficiency of the apparatus. The main haulage cable 38 leads from the slusher hoist 40, located beyond the raise 10 to the pulley or sheave 41 located in the Working face of the slice. Lead and tail cables 42 and 43 respectively, connect the scraper 13 to one section of the main cable, which section is deflected around the corner at the junction of the slice with the mining drift by the system of rollers described, the cable being supported vertically by the horizontal roller 32 and being held in position thereover by the spaced vertical rollers 26 located to the respective sides of the horizontal roller. The successful operation of the device depends upon the proper adjustment of the vertical rollers with respect to the horizontal roller and it will be seen that upon proper adjustment the lead and tail cables will readily pass over the rollers to thereby cause a change in the direction of travel of the scraper. To facilitate operation of the device the lead and tail cables are provided with weights 44 causing the cables to sag to minimize interference between the cables and the rollers.

It is to be understood that I do not wish to be limited by the exact embodiment of the device shown, which is merely by way of illustration and not limitation, as various and other forms of the device will be apparent to those skilled in the art without departing from the spirit of the invention or the scope of the claims.

I claim:

In a device of the character described, in combination, a member having supporting flanges at an angle to each other, spaced studs threaded into one flange and carrying a roller on the depending end thereof respectively, a stud threaded into the other flange and carrying a roller on the projecting end thereof, said last mentioned roller being disposed between and in substantially the same horizontal plane as said spaced rollers.

3. In a device of the character described, in combination, a member having supporting flanges at an angle to each other, spaced studs threaded into one flange and carrying a roller on the depending end thereof respectively, a stud threaded into the other flange and carrying a roller on the projecting end thereof, said last mentioned roller being disposed between said spaced rollers, and adjustable fastening means carried by the member for securing the same to a support.

In a device of the character described, in combination, a member having supporting flanges disposed at right angles to each other, one flange being horizontal and having spaced studs threaded into said flange and carrying rollers on the depending ends thereof, a stud threaded into the other flange and carrying a roller on the projecting end thereof, said spaced studs providing vertical axes for the rollers and said second mentioned stud providing a horizontal axis, and slap rollers located to the respective sides of said horizontal flange.

5. In a device for deflecting a haulage cable, comprising in combination, a supporting member disposed substantially vertically and having a horizontal flange projecting therefrom, a pair of spaced rollers carried on the depending ends of studs secured to said horizontal flange, a roller carried on the projecting end of a stud secured to the support and being located intermediate the spaced rollers whereby said haulage cable is supported in two directions by said rollers, and lead and tail ropes spliced to said cable have passage with respect to said device.

6. In a device for deflecting a haulage cable, comprising in combination, a member disposed substantially vertically and having a horizontal flange projecting therefrom, studs threaded to said horizontal flange and supporting rollers on their depending ends, whereby said rollers can be adjusted vertically with respect to the flange,

a stud threaded to said support and mounting a roller on the projecting end thereof, said last mentioned stud being located intermediate the spaced studs and in a horizontal plane where the roller mounted thereon will cooperate with said depending rollers, whereby a haulage cable is supported by said rollers against movement in two directions and may be readily attached or removed from said device.

'2. In a device for deflecting a haulage cable, comprising in combination, a member providing supporting flanges disposed at an angle to each other, studs secured at one of their ends to said flanges, and having an unsupported projecting end, rollers mounted on the projecting ends of the studs and having rotation on axes at an angle to each other whereby the haulage cable is suppcrted in two directions by said rollers, and whereby lead and tail ropes spliced to said cable have passage with respect to the rollers.

8.
